IPC: H03J5/12
Filed: 1969-08-13
Abstract: 1,253,438. Catch fastenings. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 13Aug., 1969 [16 Aug., 1968], No. 40521/69. Heading E2A. [Also in Divisions F2 and H3] A push button set for a radio receiver has a plurality of push-buttons 1, each capable of actuating two driving rods 9, 11; 13, 15 which are adapted to drive a tuning mechanism and on successive depressions of a push button the two rods are actuated alternately by an alternating mechanism 27, 31 and 47 adapted to engage first one and then the other of the driving rods. As shown a button 1 is in the released position after having been pressed to actuate via bolt 27 driving rods f3, 15. On next pressing the button 1, the gear 33 (Fig. 2) is moved anticlockwise together with driving gear wheel 31 which moves the bolt frame 27 to'the dotted upper position shown in Fig. 1 so that the button actuates rods 9, 11. The gear 33 now occupies the dotted position shown in Fig. 2 and is held against rotation by spring biassed driving pawl 35. The pawl 35 may be formed by two parallel beams 63. The rods such as 13, 15 may operate a known tuning setting arrangement (Figs. 5 to 7, not shown), in respect of which the modification draws attention to Patent No. 1,028,073. In this arrangement a segment adjusting element (51) is released from a locked position by pulling the button 1. The bolt 27 then engages the rod 13 and moves the rod relative to the rod 15 so that a U-shaped bracket (55) releases the adjusting element (51). The gear 31 and bolt frame 27 then occupy the lower dotted position in Fig. 1 and, although the gear 31 has moved, on repressing the button it resumes its position with tooth a against lug 47 for actuating rods 13, 15 so that the segment element (51) is rotated and locked to the new selected position of a tuning crank (59) by the U-shaped bracket (55). The bolt 27 may be in the form of a plate having projecting lugs 47, 49. Each driving rod 9, 11 and 13, 15 may have a lug which moves a spring returned slidable cover so that a light source is visible behind an aperture above that respective driving rod last pressed. The push button set may be used in a car radio.

Title: Amusement device
IPC: A63F5/04
Filed: 1974-09-23
Abstract: 1478693 Fruit-machines SEEBURG CORP OF DELAWARE 23 Sept 1974 [27 Sept 1973] 41238/74 Heading G4V An amusement device has reels 8, 10 and 12 mounted on a shaft 42 by means of one-way clutches 50. Thus the reels are free to rotate after they have been driven by shaft 42 which has subsequently been stopped. A motor 60 drives a shaft 74 via chain 66. At one end of the shaft there is a cam wheel 76 having a follower 82 fixed to a link 84. The link is in contact with a stud 90 on wheel lever 92 which is biased clockwise by spring (96) Fig. 5 (not shown). Thus as motor 60 rotates shaft 70 clockwise link 84 is rotated clockwise and lever 92 is rotated anticlockwise against spring (96). When follower 82 reaches offset (80) on the cam the spring rotates wheel lever 92 rapidly which causes the reels 8, 10, 12 to rotate clockwise. The reels are attached to star plates 100, 102 and 104. Associated with the star plates are, respectively, stop levers 108, 110 and 112. These levers are pivotally mounted on shaft 114 and are biased by springs 118 so that rollers 126, 128 and 130 engage the star wheels. Control of such engagement is by cam followers 120, 122 and 124 and stop cams 132, 134 and 136 which are mounted on and rotated by shaft 70. Each cam has a high portion that engages the cam followers prior to rotation of the reels and releases the levers to stop the reels in the order, reel 8, reel 10, then reel 12. To determine a winning combination the star plates have holes 140 with pins 142 positioned in some of them. Associated with each star wheel is a feeler arm 140 mounted on shaft 144. At one end of the shaft a lever 148 has a cam follower 150 which can engage with feeler cam 152 mounted on shaft 70. The feeler arms are biased toward the star wheels by a spring engaging hooks 154. In operation the cam rotates the shaft 144 so that feelers 146 are moved clear of the star wheels, prior to rotation of the reels. After stopping of the reels a step in the cam allows shaft 144 to be rotated by the springs and the feelers move toward the star wheel until they engage a pin 142. Each feeler arm has a feeler wiper (234) Fig 2 (not shown) which contacts a strip (236) on each side of a printed circuit board (238) to provide an electrical circuit to determine if a winning combination has been obtained. Slots in the end walls 34, 36 enable the shaft assemblies to be put together externally of the device and then mounted in the device. Electronic circuitry allows up to 5 coins to be used successively to increase a winning score if a winning combination has been obtained by a user. A cam (240) Fig. 6 (not shown) controls the sequential operation of the machine and a variation of the time duration that the reels spin is controlled by a varistor cam (262).

Title: Improvements in or relating to Hydrostatic Extrusion Processes
Inventor: THOMPSON PETER JOHN
IPC: B21C23/01
Filed: 1966-09-15
Abstract: 1,188,116. Extruding. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 14 Sept., 1967 [15 Sept., 1966], No. 41332/66. Heading B3P. A billet 65 with a tapered rear end 67 is extruded through a die 52 by hydrostatic pressure supplemented by direct mechanical loading; the hydrostatic pressure being reduced gradually to atmospheric as the tapered end passes through the die. The direct loading may be applied to the extruded product by a drawing device 66 or pressure may be applied by a ram to the rear end of the billet. Container 51 is connected by passage 53 to a pressure liquid cylinder 49 containing a plunger 48 and sealing gland 50. Plunger 48 is connected to a double-acting piston 46 working in cylinder 43. The underside 56 of piston 46 is supplied with pressure liquid by supply means 57 through metering valve 58, and is also connected through metering valve 59 with an hydraulic accumulator 60, 62 loaded by a gas bottle 64. The upper side of piston 46 is supplied with gas pressure through duct 55. In operation, this gas pressure causes the piston 46 and plunger 48 to move downwardly and pressurize the liquid in containers 49, 51, whilst liquid in space 56 is displaced through metering valve 58. The hydrostatic pressure produced in container 51 supplemented by the pull of drawing device 66 effects the extrusion of the larger diameter portion of the billet through die 52. As the tapered end 67 passes into the die, the hydrostatic pressure in cylinder 51 is gradually reduced by closing valve 58 and opening valve 59 whereby the accumulator 60 applies upward pressure to piston 46. As the small diameter end portion 66 enters the die the hydrostatic pressure has been reduced to atmospheric whereby extrusion is then effected wholly by the drawing device 66. Alternatively the hydrostatic pressure may be reduced in steps (C<SP>1</SP>-X) (D 1 -y). Fig. 2 (not shown). In another embodiment, Fig. 1 (not shown), the container (1) is connected directly to the hydraulic chamber (13) of a gas loaded accumulator. The gradual or stepwise reduction in hydrostatic pressure is caused by reducing the gas pressure in the accumulator.

Abstract: 1,088,768. Interconnection sheets and members. G. J. DOUNDOULAKIS, and H. DOUNDOULAKIS. Oct. 12, 1964 [Oct. 14, 1963], No. 41540/64. Heading H2E. [Also in Divisions D1 and H2] A fabric, Fig. 1, is woven with wires 11, 12 and insulating threads 8, 14 in both warp and weft, the pattern being such that selected warp wires touch weft wires (e.g. at 22, 23) to make electrical contact which is made permanent by spot welding before the fabric leaves the loom. When a length corresponding to one circuit has been woven, a hot wire is traversed across the fabric to sever the insulating warp threads 14 without affecting the wires; the fabric is advanced and a second cut is made, thereby removing pieces of thread but leaving the wires intact. The fabric then passes to a station, Fig. 8, at which rigid insulating blocks 242 are applied to the exposed wires, the blocks having metal elements 252 which are crimped on to the wires; the crimping also secures resistors 25 or other components, the wire ends of which pass through conical holes 246 and are bent by a pusher blade 270. The joints may also be dipped in solder. Alternatively, the blocks 242 may be omitted, the components being attached directly to the warp wires as indicated in Fig. 1. The fabric may be impregnated with polyester resin to stiffen it and provide further insulation between the wires that cross without touching.
